. PatentedJune 19, 1945 2,378,428 vSIDING CUTTER Frank A. odian, Detroit, Mich. applicati@ June 23, 1944, serial No. 541,835 i 4'o1aims. (C1.164-77 This invention relates to a portable hand operated machine more particularly intended for the cutting rof brick siding such as is commonly applied in the re-facing of houses.

This siding generally comes in sheets which are cut by the workmen usually with a saw to suchsizes and shapes as may be necessary for the proper fitting to the structure being covered. Such cutting is not only a fairly slow and difcultfprocess, due to the construction of the sidingy which usually includes several materials such as tar, felt, fibrous filler yand Afrequently a highly abrasive coating, which materials, especially in combination, readily foul and dull the teeth of the saw so that it must be frequently cleaned and re-sharpened, often being rendered practically useless in a very short time. The alternative of using knives, which is sometimes resorted to, still imposesconsiderable difficulty involving the expenditure of too much time and excessive energy.

The present invention has for its object to provide a simply constructed and easily operable machine which willreadily cut such material as brick siding in a highly satisfactory and speedy manner without fouling ofthe cutting elements and without excessive labor whereby an operator can accurately and cleanly cutl a much greater vquantity of siding in a given time than has heretofore been generally possible. l

The said invention still further yprovides for the cutting of material such as brick siding by co-acting knives operating on the upper. and

under sides of the material and carried by guided supports coupled for simultaneous movement in a common direction and driven by common means. l

yA further object in the invention is to provide for the lubrication of at least one'oi the knives entering the tar, or similar j adhesive layer or layers of the siding, witha suitable grease or iluid intended to prevent such layer or layers from sticking to the knife or otherwise offering undue resistance to its progress.

Still further objects kor advantages additional or subsidiary to the aforesaid objects or resulting from the construction or operationof the invention as it may ybe carried into effect will vbecome apparent as the said invention is hereinafter further disclosed. l' l In, carrying the said invention into effect I may provide a structural frame having upper and lower longitudinal horizontal guides, each supporting a slidable member, a slotted table between'said vupper and lower guides, the lower slidable member carrying a disc cutter projected upwardly through the slot of said table, the upper slidable member carrying a disc cutter above and slightly overlapping the projecting portion of the lower cutter, a crank-operated winch on said upper slidable member, and cables connecting said winch with said upper and said lower slida'ble members in such manner that the rotation of said winch inr one or other direction will effect the synchronous movement of both of said slidable members toward one or other end of said structural frame. All of whichv is more particularly described and ascertained, by way of eX- ample, having reference to the accompanying drawing, wherein;

Figure 1 is an elevation of a siding cutter embodying the said invention;

Figure 2 is a plan of the same; and v Figure 3 is a transverse section ofthe same taken on a plane indicated by the line 3--3 in Figure l.

Similar characters of reference indicate similar parts inthe several gures of the drawing.

The structure illustrated shows end frame members made up of angle iron legs I0 suitably connected together as by upper and lower straps II andv I2 for convenience.

A pair of channel iron rails I3 connect the upper ends of the end frames together and a similar. pair of channel iron rails I4 connect lthe said end frames together at a point materially below the plane of the upper rails I3, the said rails I3 and I4 together with the said end frames, thereby forming an. elongated open benchlike structure characterized by the upper and lower spaced parallel pairs of rails. Between these pairs ofrails is arranged a longitudinally slotted work supporting table I5 and I6 indicating the slot in the said table.'

` I1 and I 8 are carriers supported respectively by the rails I3 and I4 for longitudinal movement therealong which movement is facilitated by the said carriers beingprovided with rollers I9 and ZG'riding in the channels of the said rails. And on the upper rail I3 is mounted a winch 2l operable by the crank 22 and having cables 23 and 24 wound thereon for simultaneous operation by the winch, the two lends of each of the cables v23 and 24 being connected to opposite ends of the carriers I9 and 20 in such manner that rotation of the winch 2| in one or other direction will pull both of the said carriers I9 and 2l) simultaneously toward one or other end of the elonl gated structure described.

Any suitable system` of connection to accomplish this purpose may be adopted and in the present case the cable 23 is shown as passing overpulleys 25 carried by adjustable supports 26 arranged in the end portions of the rails I3, the ends of the said cable 23 then being connected to eye bolts or brackets 21 on opposite ends of the said upper carrier I1.

Similarly the cable 24 passes over pulleys 28 carried by the adjustable supports 26 and thence over pulleys 29 arranged below the Work table l5 and finally the ends of the said cable are connected to eye bolts or brackets 30 on opposite ends of the lower carrier I8. The hand wheels 3| mounted on the threaded rods 32 extending through the frame and straps l I from the members 26 serve to effect the adjustment of the said members in the rail ends for the suitable tensioning of the cables.

33 is a dios cutter carried by the carrier I8, its

periphery extending upwardly through the slot l 6 L of the work table l5 and 34 is a similar-disc cut` ter mounted on the under sideof the 'upper carrier Il in such manner that its lower periphery substantially meets or overlaps the upper pe ripheral portion of the cutter 33 and in order that this relationship between the two cutters may be varied to meet the desires of the user or to permit readjustment of the cutters after regrinding. Adjustment means may be provided Vsuch as a simple clamping bolt 35 passing through a Y bracket 36 in which a holder 31 of the said cutter 34 is vertically slidable.

38 are stops at either end of the Work table I5 against either of which the end or any portion of a slab of siding lmay abut for positioning purposes and when the work is so placed on the said table, either squarely with or at an angle vto the slot I6 the said disc cutters may be moved in the required direction to eifect the severing of ,the work along the line of the said slot by simply rotating the winch in the desired direction. Obviously there may be practically no lost motion in the use of the machine as cutting may be effected in both. directions of travel so that wheny a piece of work has been severed by moving the cutters towards one of the stops 38 another piece oi work is simply placed in position against the other of the said stops and the cutters moved back through this second piece of Work.

The upper cutter is intended to effect the major portion of the cutting inasmuch as the work is supported underneath by the table l5 and the lower cutter simply scores or makes a relatively light cut from the under surface of the work to substantially complete the severing of the ma- "3" terial. In the drawing, the projection of the lower cutter above the table is exaggerated as the depth of cut of said lower cutter may be only, say, one-tenth that of the upper cutter in many cases. y

Obviously the main upper cutter 34 is rolled through the several layers of the siding during the operation which is a most effective way of cutting material of this character as 'both pressure and shear are involved in an eilicient manner; and to prevent or minimize the tendency 4of material such as resin and tar often incorporated in such siding to adhere to the cutters and resist their operation, I provide a reservoir 39 to feed a suitable lubricant or solvent, such, for instance, as kerosene, to the cutter 34, which reservoir may be of any convenient type to contain the said lubricant or solvent and. control its flow to the Said cutter.

In actual use the described device has proved itself to be both fast and highly efficient in the cutting and trimming of such materials as brick siding commonly considered quite difficult to shape to size, and is both accurate and easily operable without calling for any special skill on the, part of the operator other than his ability to recognize the correct position in which theA Work is to be placed on the table for any particular cut to be made.

This invention may be developed within the scope of the following claims without departing from the essential features of the said invention, and it is therefore desired that the specication and drawing be read as being merely illustrative of a practical embodiment of the said invention and not in a strictly limiting sense.

What I claim is:
